MAM90AO2: Bultfonteinite with Andradite and Shinichengite

A novelty for 2021. Shinichengite (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite) forms small fibrous spheroidal coatings of an intense pink color that accompany spheroidal growths of Bultfonteinite, of good size and of an orange-brown color. On massive Andradite matrix with some small crystals at the base. The specific spot at the locality where the find was made has already been closed, so no new discoveries can be expected in that specific place.
